Abstract
Embodiments of the present invention are directed to a system and method for indoor wireless optical communication. The system may include a central unit and a plurality of user units. A bi-directional optical communication link may be established over a collimated invisible light beam to enable transmission of wireless communications between a remote communication device and a user unit. The central and user units include an optical transmitter. At least one of the user unit and the central unit comprises a visible light source configured to produce a collimated visible light beam to enable alignment of the user unit and the central unit upon establishment of the bi-directional optical communication link.
